Remarks

  • GEL PU SEALANT may be overpainted with water based paints, however due to the large number of paints and varnishes available we strongly suggest a compatibility test before application.
  • Do not use in applications where continuous water immersion is possible
  • GEL PU SEALANT has a good UV resistance but can discolor under extreme conditions or after very long UV exposure
  • Discoloration due to chemicals, high temperatures, UV-radiation may occur. A change in color does not affect the technical properties of the product
  • Contact with bitumen, tar or other plasticizer releasing materials such as EPDM, neoprene, butyl, etc. is to be avoided since it can give rise to discoloration and loss of adhesion
  • Not suitable for food contact applications.
